Magda comes out for gay marriage

Actress Magda Szubanski has pledged her support for gay marriage in a Valentine's Day statement in which she reveals her own sexuality.

"I am 1,000 per cent in favour of gay marriage," Szubanski said in the statement.

"We pay taxes, fight wars for this country, nurse you when you are sick, make you laugh, sing and dance for you, play netball for you, star in your movies, cook your meals, decorate your store windows.

"And, chances are, gay people designed whatever it is you're wearing.

"All Australians, including gay Australians, should have exactly the same rights, including the right to love, marry and take care of our partners."

The film and TV star said the current marriage law was unfair.

"The law means that you could be a serial killer and have killed all of your spouses and yet you would still be considered fit to marry," she said.

"But if you are gay, then you are not worthy of these same rights."

Her statement comes a day after two separate bills to legalise same-sex marriage were introduced in Parliament - first by Australian Greens Lower House MP Adam Bandt and independent Andrew Wilkie, and then by Labor's Stephen Jones.
